Hi. When you are in relationship understanding each other is very important. Unnecessarily fighting should not be there.since he has blocked your number take a short time to correct your self. Try to understand on wat mistakes you have committed. You must be matured enough to handle things. Dont go to depression. Sit and analyse yourself. If u r unable to cope Ur self see a counsellor. They will help you. Try to write him a letter or so.
